ESL55 LED ALF Ex – Explosion-Proof Luminaire for Precision Light Guide Applications

The ESL55 LED ALF Ex is engineered for targeted, high-intensity illumination inside reactors, containers, and specialised process equipment located in potentially explosive environments. Designed for both gas (Zones 1 & 2) and dust (Zones 21 & 22) hazard areas, this luminaire is purpose-built for applications requiring precise, localised lighting.

Unlike general-purpose Ex luminaires, the ALF variant is specifically developed for light-guide duties, enabling clear, reliable visibility in challenging or confined process zones where standard illumination falls short.
